I have a Puget desktop from 2009 and windows got corrupted and unbootable somehow, so I'm going to replace the OS hard drive (80 GB Seagate ST380815AS, SATA 3.0 GB/sec with ASUS P6T Deluxe Motherboard) with an SSD, probably 120--128GB since I found 80 GBs getting a bit tight even for the OS drive.
Any suggestions for what SSD I should get, and anything else to watch out for in upgrading. I assume I can just unplug power and cables from the old HD and plug them into the new SSD? Also I guess this motherboard supports SATA II (3.0 GB/s) but not SATA III so they'd be no benefit in getting a SATA III compatible SSD. Is that correct?
